GAS FEEDING AND MIXING DEVICE.

Specification of Letters Patent.

Patented Apr.

Application filed March 3. 1909. Serial No. 481.101,

To all who/n it may; concern:

furnaces; and it consists in the particular construct-ion, arrangementand combination of parts which will hereinafter be fully described.

The primary object of the invention is to provide a, device which isadapted to be regulated for thoroughly mixing; with air the 'gassupplied to a furnace, thereby effecting perfect combustion andmaterially reducing the quantity of gas required. I

Another object to provide a device whereby a blast may be supplied fordirecting the gas any required distance into the combustion chamber ofthe furnace.

A further object is to provide, in connection with'a gas burner, meansfor mixing air with the gas prior to its discharge into the furnace, andmeans for furthermixing air with the gas after it is discharged andbefore it reaches the point in said furnace where combustion takesplace. Anda still further object of the invention is to provide a simpleand inexpensive device of the character mentioned having regulatingmeans whereby the amount of air admitted for producing or effectingperfect combustion may be readily controlled.

In describing the invention in detail, reference is herein had to theaccompanying drawings, forming a part of this specification, in Which-Figure 1 is an elevation of a portion of a furnace showing a battery ofdevices embodying the feeding and .mixing portions of the inventionapplied thereto, and illustrating the damper-operating mechanism; Fig. 2is a vertical section. of a furnace wall, illustrating theapplication-of the invention,

the latter being" shown in side elevation;

Fig. 3 is a section on the line 3-'3, Fig. 1; and Fig. t is aperspective view of the gasdischarge nozzle, or burner.

Referring to said drawings, in which like reference numerals designatelike parts throughout the several views-4 indicatesa furnace wall inwhich is pro'videdxone or more gasieed openings 2 in which is fittedhorizontally the cylindrical discharge end{ or horn 3 of a substantiallyL-shapedhollow metallic shell 4 Whose opposite or c'eiving end or horn 5stands substantially vertical on the outer side of said wall. and has aflared or bell-shaped air-intake mouth 6. Directed horizontally throughthe wall of the shell t sons to stand substantially central of thedischarge end 3 thereof-is a branch gas-supply pipe Twhich leads fromasupply pipe 8 an has a burner or nozzle 9 upon'its end, as shown. Whileany propriate form of nozzle may be employed, I prefer to use a nozzleor" knob-shaped or bulbous formation having a plnraiit of.

perforations therein, as shown, such'no .ie being particularly adaptedfor disch the gas in different directions. its is ohvious, the shel 4provides for the there" mixing of the air with the gas i is r chargedthrough the nozzle, a strong draft or suction being produced for drawingair through the shell into the furnace. A damper 10 is provided in thevertical h or end 5 of the shell whereby the on. of air admitted throughthe latter .2 regulated.

For partially mixing the gas prcvion' its discharge from lthe nozzle. aher mixing bell 11 is provided on the pipe rectly in the rear of theshell as shown, said bell being inclined rearward, or away from saidshell, and having its flared mouth 12 located .at a point suh'icieutlyremote from the intake mouth 6 of the shell that the draft through theformer is not percepti-,

bly. disturbed bv the iurush of air through the mouth of the labter.

From the foregoing it is apparent that a most thorough mixing of airwith the gas is providcd'for by the construction described. T he damper10 being properly adjusted, the

- necessary amount or quantity of air required for producing perfectcombustion is admit-- ted. lilowever, the shell not only provides forthe proper mixing oi'air with the gas in the furnace, but also for theadmission of a quantity of air with such force tlr serves as a blast fordirecting said g desired distance into the furnace before con: bustionproper takes place.

tally through the wall of said.

The devices composing the invention may he applied to a furnace singly,or in the form ot a battery, shown in Fig. 1. In the latter case, ahorizontal gas supply pipe is provided from which the pipes branch atthe proper points, and the damper-spindles 14 'journaled in the shells tare preferably connected or coupled. form a common operating shaft. As ameans of operating said sha ft, for adjusting the connected dampers inunison, a sprocket wheel 15 may be located thereon and said sprocketWheel connected by a sprocket chain 16 to a second sprocket wheel 1'?mounton a suitable bracket 18, the latter being preferably mounted uponthe furnace wall 1.. A crank 19 mounted on the spindle of the wheel 17is turned for effecting the manipulation of the dan'ipers. The pipe 7 isof such length that when the nozzle 9 is applied thereto, the latterstands in the rear of the inner end of the opening '2. Thus, theadmitted through the shell permitted to mix with the discharged gasprior to its ontrance 'into the furnace. the force of the blast admittedthrough the shell, the whole body of the gas discharged n'iay heiliz'ecled to any desired point before combustion proper is permitted.

llaring thus described my invention, what I claim as new, and desire tosecure by Letters Patent,

1. The combination with a furnace wall having a hole therein, of ahollow metallic L-shaped shell having one horn ni nnn';ed horizontallywithin said hole and the other horn dcymnding on the outer side of saidwall, a gas-supply pipe directed. horizonshell and staxulinrg centraloi: said horizontal horn, a burner nozzle on the end of said pipe, adamper for controlling the admission of air through said shell, andmeans associated with said pipe in the rear of said shell for mixing airwit the prior to the discl'iarge of the la 1' through said nozzle.

2. The combination with a furnace wall having a hole therein, of ahollow metallic together to l l l i Further, through tally throughburner nozzle on L-shaped shell having one horn mounted horizontallywithin said hole and the other horn depending on the outer side of saidwall, a gas-supply pipe directed horizonthe wall of said shell andstanding central of said horizontal horn, a the end of said pipe, adamper for controlling the admission of air through said shell, and amixin f bell connected to said pipe in the rear oi said shell whereby apartial mixing of air with the gas is effected prior to the discharge ofthe lattcr through said nozzle.

the combination with a furnace wall having a hole therein, of a hollowL-shapcd shell having one horn mounted horizontally in said hole and theother horn depending on the outer side of said wall, agas-supply pipedirected horizontally through the wall of said shell and standingcentral of said horizontal horn, a .la.1nper for controlling, the:uhuissirm of air tl'irough said shell, and a horu-liln; mixing bellconnected to said pipe in the rear of said shell and inclined away fromthe latter.

The combination with a furnace wall having a plurality of holes therein,of a hollow metallic L-shaped shell for each hole, one horn of saidshell being directed horizontally into said hole and the other hornthereof hanging on the outer side of said wall, a gas-supply pipedirected through the wall of each shell and standing central of saidhorizontal horn, gas-spreading discharge means carried by the end ofsaid pipe in the rear of the inner end o'l said hole, a damper for eachshell, means for opcrati-ng said dauumrs in unison, and means associatedwith each supply pipe whereby the gas is partially mixed with air priorto its (llsclmi'gt. i
